i'm using a quad core, 9100 GeForce and the frame rate is unbearably slow. may not just be your computer.
If I SHUT DOWN, not restart, the computer, then start it up again and play the game, it runs awesomely for about 3 minutes... then the frame rate drastically dips to an unplayable level.
Might be some software running along with the game... not sure.
^lol 9100 get yourself a 9800gt at least.
Anyway, post the specs of your laptop, but I'm guessing it has integrated graphics which is barely enough to run this game, and there is nothing you can do about it except get a new PC.
My specs are:
Intel i5 750
ATI Radeon 5870
Asus P7P55D MOBO
4 GB G.SKILL RAM
750W OCZ PSU
